A massive dust storm swirling reddish-brown clouds over northern Oklahoma triggered a multi-vehicle accident along a major interstate Thursday, forcing police to shut down part of the heavily traveled roadway amid near blackout conditions. In a scene reminiscent of the Dust Bowl days, choking dust suspended on strong wind gusts shrouded Interstate 35, which links Dallas and Oklahoma City to Kansa ... read more >>
While some rain has hit the parched earth, the central United States is still suffering from the severe drought this past summer. Now, a University of Missouri atmospheric sciences expert from the College of Agriculture, Food and Natural Resources is predicting a mild and slightly warmer than normal winter this year, and an MU soil scientist says that the drought's effects will linger for months ... read more >>
West Texas is on the front lines of a changing climate, and scarce water is the most obvious symptom. Everyone – ranchers, farmers, water engineers – is talking about it.
A cyclone of hotter temperatures, more people, water-sapping cotton farming and a devastating 2011 drought have crippled groundwater supplies. And, though the drought has lifted, West Texans are being forced to change their way ... read more >>
Waterfront communities from Southbank to the Mornington Peninsula face a damage bill of more than $1 billion from severe storms and rising sea levels over the next 90 years, according to a confidential climate change report. The report, by federal, state and local governments, warns that parts of Rosebud foreshore could be completely submerged by 2100 during coastal flooding, while residents arou ... read more >>
Aquatic ecosystems have the potential to release more carbon dioxide (CO2) into the atmosphere in a warmer climate than their land counterparts, says a study.
In the largest ever analysis of rates of respiration, scientists at Queen Mary, University of London, have compared the temperature dependence of respiration between aquatic and land ecosystems. ... read more >>
Two small Pacific Island nations called on the United Nations this week to facilitate immediate action and a legally binding agreement to curb global warming, which has caused steadily rising ocean levels, immediately threatening the soon to be submerged states.
In separate speeches at the UN 67th General Assembly this week the leaders, President Christopher Loeak of the Marshall Islands and Pre ... read more >>
In September 2012, a week-long rainstorm in southern Alaska pushed multiple rivers over their banks. On September 21, the Anchorage Daily News reported that the Susitna River rose so much that it backed up into its tributaries, and some residents described the floods as the worst they had witnessed in 30 years. Floods closed roads, destroyed more than a dozen homes, and damaged more than 800 othe ... read more >>
U.S. Forest Service and Oak Ridge National Laboratory (ORNL) scientists have found that rising levels of ozone, a greenhouse gas, may amplify the impacts of higher temperatures and reduce streamflow from forests to rivers, streams, and other water bodies. Such effects could potentially reduce water supplies available to support forest ecosystems and people in the southeastern United States. Impac ... read more >>
Profitable climate fixes are too tempting for rogue geoengineers to resist | Adam Corner | Environment | guardian.co.uk
Geoengineering – the possibility of using large-scale technologies to counteract the effects of climate change – has arrived. The question is, are we ready for it?
From a scientific perspective, the answer is "not yet". Very little is known about any of the technologies that we might one day use to seize control of the global thermostat. Some sound like science fiction and will probably remain ... read more >>
Water is essential to nearly every economic activity and all ecological systems. It underpins a range of economic activities including farming, energy and industry. The water challenge encompasses a range of issues from both the demand and supply sides. Supply can refer to a quantity of water (volume) or a quantity of water at a sufficient quality level to enable a particular use. Insufficient su ... read more >>
